What is the sound intensity level in decibels? Use the usual reference level of I0 = 1.0×10−12 W/m2.

L = 130 decibels

Explanation:

The computation of the sound intensity level in decibels is shown below:

According to the question, data provided is as follows

I = sound intensity = 10 W/m^2

I0 = reference level =

Now

Intensity level ( or Loudness)is

Therefore  

L = 13 bel

And as we know that

1 bel = 10 decibels

So,

The  Sound intensity level is

L = 130 decibels
